Support for sub-albums

[jose1711]

It would be really great if Remot Sync supports a hierarchy like this:

2002/04/[image01.jpg image02.jpg image03..]
2002/03/[image01.jpg image02.jpg image03..]
2001/03/[image01.jpg image02.jpg image03..]
2001/01/[image01.jpg image02.jpg image03..]
2000/12/[image01.jpg image02.jpg image03..]
2000/11/[image01.jpg image02.jpg image03..]
2000/10/[image01.jpg image02.jpg image03..]

Currently it converts this to a flat structure (album names only).
